getSettersAssignableFrom

public static Set<Method> getSettersAssignableFrom(Class clazz,
                                                   Type type,
                                                   boolean isStatic)

Returns all declared setter methods of fields of the given class that are assignable from the given type.

参数：

clazz - The class to get setters from, not null

type - The type, not null

isStatic - True if static setters are to be returned, false for non-static

返回：

A list of Methods, empty list if none found

getAllMethods

public static Set<Method> getAllMethods(Class clazz)

Gets all methods of the given class and all its super-classes.

参数：

clazz - The class

返回：

The methods, not null

getSettersOfType

public static Set<Method> getSettersOfType(Class clazz,
                                           Type type)

Returns the setter methods in the given class that have an argument with the exact given type. The class's superclasses are also investigated.

参数：

clazz - The class to get the setter from, not null

type - The type, not null

isStatic - True if static setters are to be returned, false for non-static

返回：

All setters for an object of the given type

isEqualsMethod

public static boolean isEqualsMethod(Method method)

参数：

method - The method to check, not null

返回：

True if the given method is the Object.equals(java.lang.Object) method

isHashCodeMethod

public static boolean isHashCodeMethod(Method method)

参数：

method - The method to check, not null

返回：

True if the given method is the Object.hashCode() method

isToStringMethod

public static boolean isToStringMethod(Method method)

参数：

method - The method to check, not null

返回：

True if the given method is the Object.toString() method

isCloneMethod

public static boolean isCloneMethod(Method method)

参数：

method - The method to check, not null

返回：

True if the given method is the Object.clone() method

isFinalizeMethod

public static boolean isFinalizeMethod(Method method)

isSetterMethod

public static boolean isSetterMethod(Method method)

判断方法是否是setter方法
For each method, check if it can be a setter for an object of the given type. A setter is a method with the following properties:

• Method name is > 3 characters long and starts with set
• The fourth character is in uppercase
• The method has one parameter, with the type of the property to set

参数：

method - The method to check, not null

返回：

True if the given method is a setter, false otherwise
